본원 발명은 밀페형 전동압축기의 전동기에 장착하는 전류온도감응형 과부하보호기 및 그 장착방법의 개량에 관한 것이다.The present invention relates to a current-temperature-sensitive overload protector mounted on an electric motor of a hermetic electric compressor, and an improvement of the mounting method thereof.

밀페형 전동압축기가 과부하로 운전되었을 경우에 모터온도와 냉내가스온도에 감응시키는 동시에 과전류에 감응시킴으로써 모터를 전원으로부터 개로(開路)하고, 모터의 소손(燒損)을 방지할 목적으로 밀페형 전동압축기의 용기내에 전류온도감응형 과부하보호기(이하 보호기라고 함)가 장착되어 있다.When the sealed electric compressor is operated with an overload, it is sensitive to the motor temperature and the cold gas temperature, and also to the overcurrent to open the motor from the power supply and to prevent burnout of the motor. A current temperature sensitive overload protector (hereinafter referred to as a protector) is installed in the container of the compressor.

제 5 도∼제 10 도는 예를들면 일본국 실개소 56(1981)-175581호 공보에 나타낸 종래의 밀폐형 전동압축기 내부장착형 보호기의 장착방법의 일예를 나타낸다. 보호기(5)는 모터엔드코일(3)의 표면에 접하여 실(4)에 의해 고정되어 있다.5 to 10 show an example of a mounting method of a conventional hermetic electric compressor built-in protector shown in Japanese Patent Application Laid-Open No. 56 (1981) -175581. The protector 5 is fixed by the seal 4 in contact with the surface of the motor end coil 3.

제 5 도, 제 6 도, 제 8 도는 모터엔드코일(3)의 상단부에의 장착예이며, 제 9 도, 제 10 도는 모터엔드코일(3)의 측면부에의 장착예를 나타낸다.5, 6, and 8 show examples of mounting on the upper end of the motor end coil 3, and FIGS. 9 and 10 show examples of mounting on the side of the motor end coil 3.

제 7 도는 종래의 보호기(5)를 나타내는 것으로, 보호기(5)의 본체는 충전부이므로 폴리에스테르필름 등의 결징필름재에 의한 절연피복(6)에 의해 덮여 있다. 절연피복(6)은 보호기(5)에 대해 폴리에스테르필름을 원통형으로 감아 접착하고, 양단은 개방되어 있으며, 제 5 도에 도시된 바와 같이 보호기(5)의 치수 ℓ1에 대해 절연피복(6)의 치수 ℓ1는 절연을 위한 공간거리를 확보하는 등에 의해 일반적으로 1.5∼2배의 길이를 가지고 있다.7 shows a conventional protector 5, and since the main body of the protector 5 is a charging part, it is covered by an insulating coating 6 made of a bleaching film material such as a polyester film. The insulating coating 6 is cylindrically wound on the polyester film with respect to the protector 5, and both ends are open, and as shown in FIG. 5, the insulating coating 6 is applied to the dimension l 1 of the protector 5, as shown in FIG. dimensions of ℓ 1) may typically have a length of 1.5 to 2 times the like to secure a space distance for insulation.

모터엔트코일(3)에 장착시에는 절연피복은 변형이 어려우므로 ℓ1의 치수가 필요하다.When it is mounted on the motor end coil 3, the insulation coating is difficult to be deformed, so a dimension of l 1 is required.

밀폐형 전동압축기는 통상 매우 소형화되어 있으므로 모터엔드코일(3)에 보호기(5)를 장착하는 것이 치수적으로 곤란했었다.Since hermetic electric compressors are usually very compact, it was difficult to dimensionally attach the protector 5 to the motor end coil 3.

그리고, 밀폐용기를 형성하는 상용기(1)와 하용기(2)를 용접하는 위치(7)에 근접하고 있으므로, 종래의 보호기(5)의 절연피복(6)으로서 일반적으로 사용되고 있는 폴리에스테르필름으로는 용기용접시에 복사열에 의해 녹아버려서 절연기능이 상실되는 문제점이 있었다.In addition, since it is close to the position (7) for welding the commercial container (1) and the lower container (2) which form a sealed container, it is a polyester film generally used as the insulation coating (6) of the conventional protector (5). Was melted by radiant heat at the time of welding the container, and the insulation function was lost.

본원 발명은 상기와 같은 문제점을 해소하기 위해, 장착이 용이하며 내열성이 뛰어난 절연피복을 갖는 보호기 및 그 장착방법을 제공하는 것을 목적으로 한다.In order to solve the above problems, an object of the present invention is to provide a protector having an insulating coating which is easy to mount and excellent in heat resistance and a mounting method thereof.

또한, 본원 발명의 밀페형 전동압축기의 보호기의 장착방법은 아라미드지방향족 폴리아미드를 원통체로 성형하는 공정과, 이 원통체 내에 보호기를 수용하는 공정과, 이 원통체의 양 단부를 초음파에 의해 용착하여 절연피복을 성형하는 공정과, 밀페형 전동압축기의 모터엔드코일의 표면에 접하여 상기 보호기를 수용한 절연피복을 실에 의해 고정하는 공정으로 이루어지는 것을 특징으로 한다.In addition, the mounting method of the protector of the hermetic type electric compressor of the present invention comprises the steps of forming the aramid aromatic polyamide into a cylindrical body, accommodating the protecting group in the cylindrical body, and welding both ends of the cylindrical body by ultrasonic waves. And a step of forming an insulating coating, and a step of fixing the insulating coating in contact with the surface of the motor end coil of the hermetic type electric compressor by the seal with a seal.

본원 발명에 관한 밀폐형 전동압축기의 보호기는 보호기본체, 이 본체를 감싸고 내열온도가 155℃ 이상의 내열절연재료로 이루어진 절연피복을 구비한 것이다. 상기 절연피복은 아라미드지를 사용하면 유효하다.The protector of the hermetic electric compressor according to the present invention includes a protective base, an insulating coating made of a heat resistant insulating material surrounding the main body and having a heat resistance temperature of 155 ° C or higher. The insulating coating is effective when aramid paper is used.

그리고, 절연피복은 단부를 초음파에 의해 용착해도 된다.The insulating coating may be welded to the end by ultrasonic waves.

본원 발명에 있어서의 밀페형 전동압축기의 보호기는 절연피복을 내열온도가 155℃ 이상의 내열절연재료로 하였으므로, 보호기에 근접한 위치에서 압축기 밀폐용기인 상용기와 하용기를 용접해도 복사열에 의해 녹아 절연기능이 상실되는 일이 없어졌다.The protector of the hermetic type electric compressor in the present invention is made of a heat-resistant insulating material having a heat resistance temperature of 155 ° C. or higher. There is no loss.

그리고, 절연피복을 초음파로 용착함으로써, 접착제 등의 유기재를 사용하지 않고, 절연피복을 형성할 수 있다.By insulating the insulating coating with ultrasonic waves, the insulating coating can be formed without using an organic material such as an adhesive.

이하, 본원 발명의 일실시예를 제 1 도∼제 4 도에 대해 설명한다. 보호기본체인 보호기(5)는 모터엔드코일(3)의 표면에 접하여 실(4)에 의해 고정되어 있다.Hereinafter, one embodiment of the present invention will be described with reference to FIGS. The protector 5, which is a protective base chain, is fixed by a seal 4 in contact with the surface of the motor end coil 3.

제 3 도는 본원 발명의 보호기(5)를 나타내는 것으로 보호기(5)의 본체는 충전부이므로 절연피복(6)에 의해 덮여 있다. 절연피복(6)은 아라미드지방향족 폴리아미드를 원통형으로 성형하고, 그 원통단부를 봉지모양으로 하여 보호기(5)를 수납하도록 용착부(8a), (8b) 를 초음파로 용착하고 있다.3 shows the protector 5 of the present invention, and since the main body of the protector 5 is a live part, it is covered by the insulating coating 6. The insulating coating 6 is formed by forming an aramid polyaromatic polyamide into a cylindrical shape, and welding the welded portions 8a and 8b with ultrasonic waves to accommodate the protector 5 with the cylindrical end portion sealed.

모터엔드코일(3)에의 장착은 제 1 도에 도시된 바와 같이, 보호기(5)의 치수 ι0에 대해 절연피복(6)은 실(4)에 의해 절연피복(6)을 용이하게 변형시킬 수 있으며, 장착치수 ι2는 ι0와 대략 동일치수가 된다.The mounting on the motor end coil 3 is shown in FIG. 1, so that the insulation coating 6 can easily deform the insulation coating 6 by the seal 4 with respect to the dimension? 0 of the protector 5. The mounting dimension ι 2 is approximately equal to ι 0 .

상기 실시예에서는 절연피복(6)의 재료에 아라미드지를 사용한 예를 나타냈으나, 내열성이 155℃ 이상의 것이라면 이것에 한정되는 것은 아니고, 예를들면 폴리이미드수지를 사용해도 좋다.In the said embodiment, although the example which used the aramid paper for the material of the insulating coating 6 was shown, if heat resistance is 155 degreeC or more, it is not limited to this, For example, you may use polyimide resin.

본원 발명에 의하면 보호기본체, 이 본체를 감싸고 내열온도가 155℃ 이상의 내열절연재료로 이루어진 절연피복을 구비한 구성으로 하였으므로, 밀페용기의 용접시의 복사열에 견디는 효과를 얻는다.According to the present invention, since the protective body, the main body is wrapped, and the insulation coating is made of a heat resistant insulating material having a heat resistance temperature of 155 ° C. or higher, the effect of withstanding the radiant heat during welding of the hermetic container is obtained.

그리고, 절연피복을 아라미드지로 하였으므로 같은 효과를 얻는다. 그리고, 절연피복의 단부를 초음파로 봉지모양으로 용착하였으므로, 접착제를 필요로 하지 않으며, 냉매분위기중에 사용해도 화학적 트러블을 방지할 수 있다.And since insulating coating was made into aramid paper, the same effect is acquired. Since the end portion of the insulating coating is welded in an encapsulated form with ultrasonic waves, no adhesive is required, and chemical trouble can be prevented even when used in a refrigerant atmosphere.
